2 Structure features and Testing principle
2.1 Structure features

2.2 Testing principle
Let a impact body whose weight is definite rush into the surface of sample, the hardness value comes
from the rate of rebound velocity and rush velocity at 1mm distance from testing surface. The
calculation formula is following:
HL=1000×VB/ VA
In which: HL——Leeb hardness value
VB——Rebounding velocity of the impact body
VA——Impacting velocity of the impact body
Output signal diagram of the impact device is as following.

4 Testing
4.1 Preparation and Inspection prior to testing
4.1.1 The preparation of workpiece surface

17
The preparation for workpiece surface should comply with the relevant requirements specified in table
3
!During the preparation for sample, the affect to surface hardness of sample caused by overheating,
cold processing and etc. should be avoided as far as possible.
!If the surface to be tested is too rough, measuring error will appear. So the surface of the sample
must have metallic luster and the surface must be flat, smooth and have no oil dirt.
!Curved surface: it is better that the testing surface of workpiece is plane. When the curvature
radius R of the curved surface to be tested is less than 30mm (for D and DL type impact device),
a small support ring or non conventional support ring should be used.
!workpiece supporting
—— Support is not necessary for heavy test workpiece

18
—— The workpiece with medium weight must be placed on flat and solid plane, and it must be
placed stably without any shaking.
!Enough thickness of workpiece is necessary, and the min. thickness should comply with the
specification in table 3.
!As for test piece with hardened surface layer, the depth of hardened layer should comply with
table 3.
!Coupling
——The workpiece with lightweight must be firmly coupled with the support; both coupled
surface must be flat, smooth and the coupling agent should not be too much. The measuring
direction must be vertical to the coupled surface.
——When the workpiece is a large area plate, long rod or bending piece, it can be deformed and
become unstable even the weight and the thickness is heavy and the test value may not be
accurate. So it should be reinforced or supported at the back of the workpiece.
!Self magnetism of workpiece should be less than 30 Gauss.
4.1.2 System setting of tester
Specific procedures for setting, refers to 6.5.

19
4.1.3 Measuring condition setting of tester
Specific procedures for setting, refers to 6.5.
4.2 Testing
!A random hardness block should be used to check the tester prior to the testing; and the reading
value error and repeatability should not be more than the specification in table 5.
Note: the hardness value of standard hardness test block can be measured via a Leeb hardness
tester which had been calibrated; five times of measuring should be carried out in direction of
vertical down and the arithmetic mean of five values should be used as the hardness value of
standard hardness test block. If the value exceeds the standard range, it can be calibrated via
user calibration function.
